Method for providing RF powder and RF powder-containing liquid
View Patent ↗Provided are a method for providing an RF powder that is easily handled because it is used as a powder (powdery state), not used as individual elements, and is high in applicability and extensibility, extremely low in manufacturing cost in respect of the unit price of each particle, and extremely high in practicability; and an RF powder-containing liquid. In the method for providing an RF powder, an RF powder composed of a large number of RF powder particles 11 a is provided to a user in a state of being stored in a container 1 . The RF powder is stored in the container 1 together with a medium that prevents the large number of RF powder particles 11 a from adhering to one another. The medium is a liquid having a specific color determined so as to correspond to the characteristic frequency of the RF powder.
1. A radio frequency (RF) powder-containing liquid comprising: a liquid; and an RF powder included within the liquid, wherein the RF powder comprises a plurality of RF powder particles, wherein the RF powder particles each include a substrate and an antenna circuit element located on a surface of the substrate; wherein the liquid has a specific color; wherein the specific color of the liquid is indicative of a characteristic frequency of the RF powder; and wherein the liquid includes a pigment and a fixative.
2. The RF powder-containing liquid according to claim 1 , wherein the RF powder included within the liquid such that the RF powder is stored and managed within the liquid.
3. The RF powder-containing liquid according to claim 1 , wherein the characteristic frequency of the RF powder is about 2.45 GHz and the specific color is substantially blue.
4. The RF powder-containing liquid according to claim 1 , wherein the characteristic frequency of the RF powder is about 2.0 GHz and the specific color is substantially yellow.
5. The RF powder-containing liquid according to claim 1 , wherein the characteristic frequency of the RF powder is about 1.5 GHz and the specific color is substantially red.
6. The RF powder-containing liquid according to claim 1 , wherein the characteristic frequency of the RF powder is from about 1.5 GHz to about 2.45 GHz.
7. The RF powder-containing liquid according to claim 1 , wherein a size of a rectangular plane having a maximum long side of the RF powder particle is 0.30 mm square or less.
8. A radio frequency (RF) powder-containing liquid comprising: a liquid; and an RF powder included within the liquid such that the RF powder is stored and managed within the liquid, wherein the RF powder comprises a plurality of RF powder particles, wherein the RF powder particles each include a substrate and an antenna circuit element located on a surface of the substrate; and wherein the liquid includes a pigment and a fixative.
9. The RF powder-containing liquid according to claim 8 , wherein the liquid has a specific color indicative of a characteristic frequency of the RF powder.
10. The RF powder-containing liquid according to claim 9 , wherein the characteristic frequency of the RF powder is about 2.45 GHz and the specific color is substantially blue.
11. The RF powder-containing liquid according to claim 9 , wherein the characteristic frequency of the RF powder is about 2.0 GHz and the specific color is substantially yellow.
12. The RF powder-containing liquid according to claim 9 , wherein the characteristic frequency of the RF powder is about 1.5 GHz and the specific color is substantially red.
13. The RF powder-containing liquid according to claim 9 , wherein characteristic frequency of the RF powder is from about 1.5 GHz to about 2.45 GHz.
14. The RF powder-containing liquid according to claim 8 , wherein the antenna circuit element is a resonant circuit that responds to an electromagnetic field from outside.
15. The RF powder-containing liquid according to claim 8 , wherein a size of a rectangular plane having a maximum long side of the RF powder particle is 0.30 mm square or less.
16. A method for providing an RF powder composed of a large number of RF powder particles in a state being stored in a container to a user, wherein the RF powder is included within the liquid; wherein the RF powder particles of the RF powder each include a substrate and an antenna circuit element located on a surface of the substrate; wherein the liquid has a specific color; and wherein the specific color of the liquid is indicative a characteristic frequency of the RF powder; and wherein the liquid includes a pigment and a fixative.
17. A method for providing an RF powder composed of a large number of RF powder particles in a state being stored in a container to a user, wherein the RF powder is included within a liquid such that the RF powder is stored and managed within the liquid; wherein the RF powder particles each include a substrate and an antenna circuit element located on a surface of the substrate; wherein the liquid has a specific color; and wherein the liquid contains a pigment and a fixative.
